HARDWARE INSTALLANTION and CONNECTIONS
It is highly recommended that quality cables and connectors be used for all video and audio source
connections.
1. The unit is designed to be rack mounted in a standard EIA 19” rack. Use the supplied rack screws to
mount the unit securely.
2. The unit comes standard with HDMI, Component, and Composite video inputs.
The CHD encoder / modulator are intelligently designed to detect the active video input from the video
source. HDMI Connection: Connect the HDMI cable(s) from the video source(s) into the HDMI
input(s). If using a Component Video Cable, connect the Y (Green), Pb (Blue), and Pr (Red) video
source cable to the unit’s Component input ports. If using a Composite Video source, use a 75Ω
coaxial cable with RCA connectors to connect the video source (e.g., CATV, DVD, VCR, Camera) to
the unit’s CVBS port (IN1…IN2 depending on the CHD model).
Repeat this step for each video source connection.
3. Component / Composite Audio inputs: Connect a Digital Audio Coaxial cable or Optical (Toslink)
cable for Digital Audio use from the audio source. For A/V audio input (Left / Right Audio) use RCA
cables to connect the audio source to the red / white AUDIO L and AUDIO R INPUT jacks (IN1…IN2
depending on the CHD model).
Repeat this step for each audio source connection.
Be sure the video and audio connections for each source are consistent with the unit’s inputs (IN1…IN2
depending on the SCDM model).
4. Use a quality 75Ω coaxial cable with “F” connectors from the unit’s RF OUT jack to the distribution
system (combiner or reverse splitter) or directly to a television.
5. Connect the included power cord to the unit’s POWER plug.
6. Connect the power cord to an appropriately rated AC power outlet.
